Cell Structure Quiz

What is the basic unit of life?

• cell

• atom

• molecule

• organism

Which organelle is known as the powerhouse of the cell?

• lysosomes

• mitochondria

• ribosomes

• nucleus

What is the function of the cell membrane?

• Stores genetic information

• Regulates cell division

• Provides energy to the cell

• Controls the movement of substances in and out of the cell.

What is the function of the nucleus in a cell?

• Control center and genetic material storage

• Waste storage

• Energy production

• Cell wall formation

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus and membrane-bound organelles.

• Eukaryotic cells lack a cell membrane.

• The main difference is the presence of a nucleus and membrane-bound organelles in eukaryotic cells, which are absent in prokaryotic cells.

• Prokaryotic cells are larger in size than eukaryotic cells.

Name the organelle responsible for protein synthesis.

• Mitochondria

• Ribosome

• Endoplasmic reticulum

• Golgi apparatus

What is the function of the mitochondria?

• Produces energy in the form of ATP

• Synthesizes proteins

• Regulates cell division

• Stores genetic information

Explain the role of chloroplasts in plant cells.

• Chloroplasts play a crucial role in photosynthesis by converting light energy into chemical energy.

• Chloroplasts are responsible for cell division in plant cells.

• Chloroplasts regulate the temperature of plant cells.

• Chloroplasts store excess water in plant cells.

What are the differences between plant and animal cells?

• Plant cells have lysosomes, while animal cells have plastids.

• Plant cells have flagella, while animal cells have cilia.

• Animal cells have a cell wall, while plant cells have a cytoskeleton.

• Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells have centrioles.

Describe the structure and function of the endoplasmic reticulum.

• The endoplasmic reticulum is a network of membranes in eukaryotic cells. It can be rough (with ribosomes) or smooth (without ribosomes). Rough ER is for protein synthesis, smooth ER is for lipid metabolism and detoxification.

• Smooth ER contains ribosomes for protein synthesis.

• Rough ER is responsible for lipid metabolism.

• The endoplasmic reticulum is a single membrane structure in prokaryotic cells.
